JOINTER ATTACHMENT FOB PLOW'S.

Specification of Letters Patent.

Patented J an. 11, 1910.

Application filed July 1, 1909. Serial No. 505,375.

To all whom "it may concern:

Be it known that I, PHILIP S. SIDELL, a citizen of the United States,and a resident of Shreve, in the county of IVayne and State of Ohio,have invented a new and Improved Jointer Attachment for Plows, of whichthe following is a full, clear, and exact description.

This invention relates to plows of a class that are adapted for sub-soilplowing, and also for cutting sod loose, and turning it as it is cutinto the furrow made by the moving plow.

Usually a cutter blade, known as a jointer, is attached upon a plowbeam, and depends therefrom in advance of the fixed colter, such anattachment being arranged for cutting sod and loose earth in advance ofthe plowshare and mold board.

The purpose of the invention is, to pro vide simple, novel means fordetachably connecting a single or double pointed jointer blade, directlyupon the standard of the plowshare and near to the mold board, formingan upward extension thereof, which will cut off vines, shear cut sod andturn such cut material as well as loose soil into the furrow formed bythe progressive movement of the mold board and plowshare of the plow.

The invention consists in the novel construction and combination ofparts, as is hereinafter described, and defined in the appended claims.

Reference is to be had to the accompanying drawings forming a part ofthis specification, in which similar characters of reference indicatecorresponding parts in all the views.

Figure 1 is a perspective view of a plow and of the improvement mountedthereon, the jointer blade being indicated by dotted lines; Fig. 2 is anenlarged transverse sectional view of a plow standard, and a plan viewof a detail of the invention mounted thereon; Fig. 3 is an enlargedperspective view of a bracket arm that is a main feature of theinvention; and Fig. 4 is a perspective view of the improvement, mountedupon a plow standard shown partially, and connected with a portion of aplow beam.

In the drawings, 5 indicates a plow beam of any preferred construction,and 6 a clownwardly-extended standard, that is secured by the upper endthereof upon the lower side of the plow beam, said standard beingrectangular in cross section, as shown in Fig. 2.

Upon one side of the standard a land-side plate 7 is secured, and nearthe front edge of the standard 6 a colter blade 8 is positioned, thatmay be formed integral with the landside plate.

A mold board 9 is secured 011 the side of the standard 6, opposite fromthe landside plate 7, said mold board having the usual concave curvatureoutward and downward as its projects rearwardly from the colter blade.

There is a plowshare 10, provided, of well known form, which is securedupon the mold board 9 and landside plate 7, having such concavity andshape of its lower edge as adapts it for penetrating the soil, andcoacting with the mold board for turning a furrow of proper depth whenthe plow is in service.

The jointer blade employed for service as an adjunct of the colter 8 andmold board 9 may be in the form of a plate metal blank 11, that has foursubstantially parallel edges and four angular corners a, as is clearlyshown in Fig. 4.

A dominant feature of the invention resides in the means employed fordetachably connecting the jointer blade 11 with the standard 6, saidmeans, as clearly shown in Figs. 2 and 3, consisting of an arm 12, thatis longitudinally slotted at one end thereof, providing two spaced jawsl2 that are adapted to closely embrace the body of the standard 6, whenapplied thereto from the front edge of the said standard. From a pointnear the junction of the aws with the arm 12, said arm is curveddownward and forward to a point 6, where said arm is widened andbifurcated, providing two diverging members l2 thereon. The limbs 12 arecurved sidewise, so as to closely fit upon the outer surface of thejointer blade 11, and in each limb 12 a longitudinal slot 0 is formed.In the arm 12, near the jaws 12 a transverse perforation d is formed,through which one limb of a looped clamp 13 is inserted, said clampbeing disposed as shown in Fig. 2, having its bowed portion c seated onthe convex surface of the arm 12 near the jaws 12 and the parallelmembers 9, 9 thereof having contact with the sides of the standard 6.The members g, 9 ex tend beyond the rearedge of the standard 6, and arethreaded for the reception of nuts h. A clamping bar z having spacedperforations therein is mounted on the threaded. portions of the membersg, g, and on the latter are screwed the nuts /L which secure theclamping bracket arm upon the standard at a desired point. The jointerblade 11 is secured upon the convex rear sides of the limbs 12 by bolts,that have countersunk heads, indicated at m in Fig. at, said bolts, thatreceive nuts on their threaded ends, pass through the slots in the limbsand clamp the limbs upon the jointer blade 11 by an adjustment of thenuts not shown.

It will be seen that by the means hereinbefore described, the jointerblade 11 may be secured a proper distance in front of the mold board 9and have one of the lower corners a, on the side edge thereof that isabove the landside plate '7, so positioned that it will cut the soil, orsod, if there is such,

to be plowed under the ground.

The iointer blade may be adjusted for height in an obvious manner, andit serves as a colter as well as a supplementary mold board. for turningthe upper portion of the soil as it is plowed, down into the furrowformed by the plow proper.

Having thus described my invention, I claim as new and desire to secureby Letters Patent:

1. In a device of the character described, the combination with ajointer blade, and a plow standard, of a bracket arm having two spacedmembers that are adjustably secured on the jointer blade, and a clampingdevice adapted for detachably securing the bracket arm on the plowstandard.

2. In a device of the character described, the combination with ajointer blade having a concave front sid and perforations therein, of abracket arm having two members bent to have close contact with theconcave side of the jointer blade, said members each having alongitudinal slot therein and bolts that pass through the slots andperforations, said bolts being adapted for clamping the members of thebracket arm upon the jointer blade.

3. In a device of the character described, the combination with a plowstandard, and a concaved jointer blade, of a bracket arm, comprising twospaced jaws on one end of the arm which embrace the standard, a loopedclamping bolt having two limbs that embrace the jaws and standard, meansfor securing the bolt limbs on the standard, two spaced plate-likemembers on the opposite end of the bracket arm, that are bent to fitupon the concave side of the jointer blade, said members each having alongitudinal slot therein, and bolts in said slots adapted for clampingthe spaced members of the arm upon the ointer blade. 7

4;. In a device of the character described, the bracket arm, comprisinga body portion having two spaced parallel jaws 011 one end, and twoplate-like members on the opposite end, spaced apart and bent downwardand forward from the jaws, each member having a longitudinal slottherein.

In a device of the character described, the combination with the jointerand a plow standard, of a bracket arm comprising an arm slotted at oneend for receiving the standard and having at the other spaced membersadjustably connected with the blade, and means for clasping the arm onthe standard.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.

PHILIP SIDELL.
